To all whom t may' concern:

Be it known 'that We, SAMUEL Josera Toon an( ALBERT 'IILToN HLX-Menu; citizens of the Vnited States gf America, at Highlund Parli; in the county -ol Wayne and Stute of ll'ichigzin, have invented certain non' and useful Improvements in lvliiling- Machines, of which the following; ii specification, reference being had therein to the accompanying drawings.

This invention relates to milling machines and attachments, and thc primary object of our invention is to provide e millingr mii-- chine having av plurality of inter-exchangeable tables that can be easily and quickly placed in position to be successively moved in the millingy machine; and thereby increase (he production ofthe machine.

A .further object of this invention` is to provide a. milling machine attachment that permit-s of one or more tables beingr used in connection with the same; one tuble permitting; of n piece of work being repeatedly operuled'upon without removing the piece of work from the table, and :i plurality of tables permitting of a large number of' pieces ot Work being successively operated upon without the usual a d j u stments.

With the above and other objects in View,

`the invention resides in the novel construction combination und arrangement of parts to be hereinafter specifically described and then claimed. v

ln describing our invention by eid of the views above referred to, we desire to point out that ne intend said i iews es merely illustrative of on exemple whereby our invention muy "1e applied in practice, und We do not .limit the invention to the exact construction and arrangement of parts shown. The following description therefore to broadly construed es includ-ing substitute constructions zind arrangements which the ohvious equivalent of those shown.

In the drawings, there is illustrated a milling machine embodying, among other things, n. column 1, an over-erm 2, :in arbor support 3, a cone spindle 4, u knee 5, and a. saddled The saddle 6 is best shown in Figs. 2, 6 and 7 wherein it will be observed that said saddle has the`ordinary guide Way 7 and is provided with side extensions 8 and 9, thereby increasing the length of the saddle over that ordinarily used in connection With milling machines. The extensions 8 and 9 are provided with Aingulzuly disposed enlargements 10nnd mounted ilrsuid enlargements nrc bushing; 11 supporting a reroluble shaft l2. The shaft l) is diagonally disposed relatively to the saddle 6; said shaft extending, through :1. recess 13 in the bottom of said saddle. Leur-:ely mounted upon the shaft 12,'\ within the recess 1S. u beveled gear wheel 14 huving: n clutch member 15 adapted to be engaged b v :t clutch member 16 slidably keyed upon the shaft 12, und adapted to rotate therewith. The clutch member 16 is moved into :ind out of engagement with the clutch member 15 of the beveled gear Wheel lfl by :i shifting device 17 operatablc at vthe front side ofthe saddle 6. It is through the medium of the shifting device 17 that the operation of theshnft 12 is controlled. At one end of the shaft 12 there is a hand crankv land a micrometer scale 19, and at'the 0pposite end of the shaft 12 there is a gear case 20 and a crank 21 which permit of the shaft l2" being rapidly revolved for a quick adjustment. The shaft l2, adjacent to the bevsled gear` wheel 14, is provided with a worm 22, and said worm is within a longitudinal way 23 that extendslongitudinally of the saddle from one extension to the other.

Especially Adesigned to move longitudi nelly or" theV saddle 6 are hollo'w oblong tables 24 which are identical in construction, one of the tables being clearly shown in Figs. 3 and 4. Each table has the top thereof provided/with the ordinary grooyes 25 that permit of a piece of work being clamped to the table by suitable fastening means engaging in the grooves 25, and each table has e dependingV hollow longitudinal dove-tailed tongue 26. Each table is of less length than vthe` saddle 6' and the extensions thereof, and

the ends ofthe guide way 7 of the' saddle 6 arek beveled or cut away, as at 98, whereby the tongues 26 can readily yenter the guide way 7, this being essential when a plurality of tables are coupled together, as will hereinafter appear. The tables 24 are provided with longitudinal depending racks'27 4that extend below the tongues .26, and-when a plurality of the tables are coupled together, the racks 27 abut, as shown in F ig. 5, thus forming one continuous rack which engages the Aworm 22 of the shaft 12. The ends of the tables 24 are cut away, as at 28, whereby one table will over-lap the other and to retain the tables 24 in longitudinal alinement and inter-locked to move in unison, the sides of the tables, at the ends thereof, are provided with spring pressed pivoted latches or hooks 29 and ontwardly'extending pins 30. The latches or hooks 29 are adapted to engage the pins 30 of an adjoining table, as best shown in Fig. 2 and in this manner the tables are detachably conec'ted whereby a table can be removed "fronil either end of the saddle 6. f

In order that one or the tables 24 and a piece of work attached thereto can be convenienti moved, two or more carriages 31 are emp eyed. These carriages are preferably made oi tubing or structural steel and are provided. with casters 32 whereby they can be easily moved about the milling machine. Adjnstably mounted upon each car ringe are the bearings 33 of longitudinal channel-shaped holders 34. The holders 34 have side .flanges 55, anti-frictional spaced rollers 3G, and grooves provi g clearance for the racks 27 si i The tongues 26 of the tables 24 are adapted to ride upon the rollers 36 and with the flanges 35 et the holders extending under the tables, said flanges serve as guards and defiectors forshavings and other matter that might interfere with the movement rof a tablelongitudinally of the holder of a carriage. it is through-the mengitudinal grooves 37, said dium of the adjustable bearings 33 that the holder of a carriage can be properly positioned to longitudinally aline with one of the extensions'or 9 of the saddle, whereby a table can readily move oli of a carriage onto an extension and through the guide way 7 of the saddle. 1t is in this connection,

that the saddle and guide way thereof are train of tables, and then the piece of work" operated upon can be removed without interfering with the operation of the millingV machiney upon other pieces of work. It` is therefore evident that should the piece of work require further operations, the carriage can be'transferred to the forward end of the milling machineand the table 'thereof again coupled to the train of tables. This is simply an instance of how the tables can be used for continuous operation in the millinmachiuef he side of the knee Shes the ordinary and well known type of trip and reverse speed mechanism 38 (see Fig. l), said mechanism having the main shaft 39 thereof detachably connected by a universal coupling 40 to a telescopic transmission shaft 41, said shaft being coupled in a similar manner to a drive shaft 42 revolubly supported by the columnv 1 of the millingA machine. The feed mechanism 38 is adapted to Iimpart movement toa gear wheel 43 mounted upon the inner end of a shaft 44 arranged longitudinally of the knee 5. Slidably keyed upon the shaft 44 is a small gear wheel 45 having a clutch .member 46. This member is adapted to engage assimiler member of a beveled gear wheel 47 loosely mounted upon the shaft 44.. The beveled gear wheel 47 normally meshes with a horizontally disposed gear wheel 48 secured upon the upper end of a feed screw 49 supported by the base of the milling machine. The feed screw 49 is of the ordinary and well known type employed for vertically adjusting the knee 5 of the milling machine.

Arranged longitudinally of the knee 5, above the shaft 44, is a shaft 50, the greater part of which forms a feed screw 51. Loosely supported atthe inner end of the @haft 50 and meshing with the small gear wheel 45 of the shaft 44 is asmall gear wheel 52 having a clutch member 53 ada ted to be shifted into engagement with a ci) keyed or otherwise secured to the shaft 50. The feedv screw 51 is'n screw ,threaded' enutc-h member 54 gz/:gement with a nut 55; supporti'fll by a, Lulmlzu homing 5G forming para; ol u. l: 5T momlwll in the lower purl ol'Y the, (3.

polso. w--` mfl of thi slulcllo to ward and of work being expeditiously operated upon, and with the holders of the carriages supporting the tables, as illustrated in Fig. 4, the tables are properly alined to be coupled and moved between the gibs, Without subjecting the same to any stresses or strains until the entire weight of a table is upon the saddle.

Practically the same results can be obtained by the attachment shown in Figs. 11 and 12 by simply couplin up the transmission shaft 41, and as befre stated, one or more tables can be used in connection with the attachment or a single table for repeated passages in the machine.

`We attach considerable .importance to the fact that the driven feed shaft 12 is diagonally disposed within the saddle of the milling machine or the saddle of the attachment to the machine, thus permitting of easy access being had to the ends of the shaft for minute and rapid adjustment thereof. Another important feature which has a distinct advantage over the old type of milling machine is that oi' applying power to the feed shaft and transmitting the saine to the tables at a point directly beneath a cette; of a millimg machine, consequently there is no tenda table 'and the piece of work carried therebyto move other than in a rue straight kine with a minimum degree oi friction behetable and the gibs of the guide waxy,
